By default, the storefront language is set to English. You can change the storefront language on the Settings tab to one of our available translations. If you do not see the language you need listed, we are able to add new translations by request for Pro and Custom customers. Please contact support to submit a translation request.
NOTE: Each storefront can only be in one language. If you need additional languages, you'll need to create a new Uscreen account but please contact the Sales team at firstname.lastname@example.org to understand how that will work.
Navigate to Settings > General Settings and scroll down to Platform Locale. You can change the language of the storefront here.
